Vector bosons and jets at the LHC

In these proceedings I review recent theoretical predictions describing processes involving vector bosons and jets at the LHC. Such processes possess very distinctive phenomenologies and their theoretical accuracy is very different. I focus here on three illustrative cases: the production of a Z boson in association with a b jet, W-pair production in association with a jet, and vector-boson scattering. Some of these theoretical results are also compared to experimental data.
